Definitions
- CD Compact Disc
- MD Mini Disc
- a standard is widely used, which has a performance that the frequency band ranges from 0 Hz to 20 kHz, the number of quantization bits is equal to 16 bits, and the audio channels are two channels.
- the low-band high-order signals, low-band low-order signal, and high-band signal which are generated from the band dividing and data producing circuit 1b are set to "A2L”, “ALQ(2/4)", and “A2H", respectively.
- the low-band high-order signal, low-band low-order signal, and high-band signal which are generated from the band dividing and data producing circuit 1c are set to "A3L”, “ALQ(3/4)", and "A3H", respectively.
- the low-band high-order signal, low-band low-order signal, and high-band signal which are generated from the band dividing and data producing circuit 1d are set to "A4L", "ALQ(4/4), and "A4H", respectively.
- the block forming circuit 2 divides those signals on the time base.
- the signals existing in the same time zone are combined and are assigned to the subblocks 0 to 8 in the information data section in Fig. 1.
- the block forming circuit 2 forms labels as identification data to indicate the kinds of data recorded in the subblocks 0 to 8, that is, the kinds of audio signal channels and frequency bands and assigns to the subblock headers 0 to 8 in Fig. 1.
- Fig. 5 shows a correspondence table between the output signals of the band dividing and data producing circuit 1a to 1d which have been recorded in the subblocks 0 - to 8 and the labels.
- the label "10" corresponds to "A1L”
- the label "14" corresponds to "ALQ”.
- "ALQ" of the label "14” denotes the combination of "ALQ(1/4)", “ALQ(2/4)", “ALQ(3/4)", and "ALQ(4/4).
- a reproducing apparatus of digital audio signals according to the invention shown in Fig. 9 reproduces only the recording information of the frequency band lying within a range from 0 Hz to 20 kHz, the number of quantization bits of 16 bits, and the audio channels of two channels from the Super CD in which the audio signals in which the frequency band lies within a range from 0 Hz to 40 kHz and the number of quantization bits is set to 20 bits and the audio channels are set to four channels have been recorded.
- the extracting circuit 91 detects the label "10" (label corresponding to "A1L”) and the label "11” (label corresponding to "A2L”) from the subblock header region of this signal and extracts the data "A1L” and "A2L” of the subblocks corresponding to those labels and supplies the extracted data to 16-bit D/A converters 92 and 93, respectively.
- the 16-bit D/A converter 92 converts "A1L” as a digital audio signal into the analog signal and generates as a reproduction audio signal channel 1.
- the 16-bit D/A converter 93 converts "A2L” as a digital audio signal into the analog signal and generates as a reproduction audio signal channel 2.
